TACKING MECHANISM.

Specification of Letters Patent.

Patented June 25, 1912.

Divided and this application filed October To all whom it may concern:

Be it known that THOMAS K. KEITH, late of Boston, in the county of Suffolk and State of Massachusetts, deceased, invented certain improvements in Tacking Mechanisms, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the sev eral figures.

This invention relates to machines for use in the manufacture of boots and shoes and particularly to tacking mechanism.

The invention is herein shown for exemnlification as embodied in the tacking mech- .;nism of a machine for working an upper over a. last and securing the same, for which use the invention has been particularly designed, although many features of the illvention are applicable also to tacking and nailing machines for general use.

The present application is a division of application Serial No. 633,693, filed April 24, 1897, in which is shown, in connection with the tacking mechanism, a lasting machine equipped with devices for working an upper into proper position. upon a last and.

clamping the same in place while being tacked. Two acks are mounted upon a carrier by movement of which the last carrying the prepared upper is brought into position to be operated upon by the tacking mechanism. Each jack is mounted for rotation about an perpendicular to the sole of the shoe at its middle portion and means is provided for automatically-rotating the same.

By this invention a machine is provided in which the shoe support and the tacker mechanism have novel movements relative to each other.

Important features of the invention are embodied in the mechanism for moving the tacker head toward and over the edge of the insole by which movement the tacker head is broughtinto proper position for driving the tacks, and the upper may or may not be wiped in and laid down upon the insole by the tacker nose; and in the mechanism by which the tacker head is uplifted and retracted from its inserting position so that it clears the overlaid upper during its return to position for the nex tacking movement.

lation from each other.

A broadly novel feature of this invention which is of prime importance consists in provision for giving to .the tacker an automatic movement longitudinally of the shoe so that at each operation the tacker head will act upon a new portion of the work. This longitudinal movement is herein utilized for moving the tacking mechanism along the sides of the shoe for the purpose of spacing the fastenings for the side portions of the upper. To carry on the tacking operation about the toe and heel portion of the shoe and to present the other side of the shoe to the tacking mechanism the last support is given a half-revolution when the toe is reached and also when the heel is reached. It is desirable for tacking along the second side of the shoe to have the tacker start from its initial position. Moreover, since the shoe rotates about an axis near its middle point, the toe portion, as the shoe rotates, has a movement back toward the initial position of the tacker. In accordance with a pre ferred arrangement embodying a further feature of this invention, advantage is taken of this rotation and backward travel of the toe portion for bringing the tacker mechanism back also to initial position for tacking the second side of the shoe. During the backward movement of the tacking mechanism, however, the rotative movement of the shoe is suiiiciently in excess of the backward movement of the tacker mechanism so that the requisite relative movement is provided between the tacker and the shoe upper for placing the tacks in suitable spaced rc- Furthermore, by this combined movement of the tacker and the shoe the tacker is made to pass over the edge of the shoe in a direction substantially perpendicular to the periphery at the point passed over.

Other features of the invention are found in the tack separating and feeding mechanism. The mechanism comprises a pivoted pick-off lever provided with an irregular slot in which a pin connected with the driver is arranged to reciprocate. The lower end of the lever is adapted for taking a tack from the end of the raceway and delivering it to the tacker head. The end of the pickoff lever is also adapted to move trans versely across the raceway and form a clo sure therefor while delivering the tack to the driver. The end of the raceway is ad jace'nt the driver and the end of the pickoff lever is provided with a notch adapted to take a tack from the raceway and deliver it to a tube leading directly to the driver, a lateral project-ion V on the pick-off lever, meantime, holding the tacks in the raceway.

These and other features of the invention, including certain details of construction and more important combinations of parts will appear in connection with the following description and will then be pointed out in the claims.

The portion of the machine with which this invention is concerned is shown in general in Fig. l in which A is the base of the machine and 1 and 2 are columns for supporting various parts thereof, the tacker mechanism being arranged on the column 1. Standards 4 and 6 bolted to the base of the machine carry respectively bearings for the main shaft 8 and the shaft 10, hereinafter referred to as the auxiliary shaft. For supporting the tacker mechanism a plate 12 is secured by bolts 13 to the top of the column 1. A rock-shaft 14 is supported in brackets 16 mounted upon the rear face of column 1. Secured to the rock-shaft 14 is an upwardly extending arm 18 having a hole in' its upper end in which is rotatably seated a pin 19 (Fig. 2) secured upon a plate 20, having ears at its ends which are pivoted by a pintle 28 to ears 22 on a plate 26, which carries the tacker mechanism.

The plate 26 carries supports 30 having bearings for a cam shaft 32 which has at one end a sprocket wheel 34 over which passes a sprocket chain 86. The sprocket chain 36 passes also about one part of a double sprocket wheel 38 in line with sprocket wheel 84 and mounted for rotation upon a stub shaft 40 supported by a bracket 42 on the rear face of the supporting column 1. Motion is communicated to the other part of the double sprocket wheel 38 by a sprocket chain 44 from a sprocket 46 fast on the main shaft 8. A single rotation of the shaft 8, by this means, transmits one rotation to the cam shaft 32, the gear ratio being one to one. The shaft 32 which may be called the tacker cam shaft has fixed thereon edge cams 50, 60 and 70. The cam 50 actuates mechanism to operate the driver. The cam 60 through a system of levers communicates to the tacker head an in and out or to and fro movement over the edge of the last bottom. The cam through its attendant mechanism gives to the tacker head a rising and falling or up and down motion. The action of the cams 60 and '70 is, however, interdependent and the motion of the tacker head is a resultant of the two movements, the effect being to cause the nose of the tacker to move in a closed path.

Forward of the cam shaft 82 upon the tacker plate 12 are supports 80 for the opposite ends of a pintle rod 82 which passes through three cam levers 51, 61 and 71, and provides a common fulcrum therefor. The power ends of the levers carry cam rolls which engage respectively with the cams 50, 60 and 70.

The lever 51 at its forward end carries a link 52 pivotally connected to it and to a lever fulcrumed intermediate its ends at 54 to the tacker head support 84. The forward end of the lever 58 is connected by a link 55 to a block 56 (Fig. secured by aset screw upon the upper end of a driver bar 57. The driver bar carries at its lower end a driver 58 and the downward move-- ment of the driver and driver bar is limited by a block 59 clamped to the driver bar by a set screw and having therebeneath. bu tfer washers 81 to diminish the shock of the blow of the driver bar. The tacker head support 84 is pivoted at 86 upon an inclined projection 88 from the forward end of the plate 12. A lever 78 is pivoted upon the upper end of the tacker head support 84 by the same bolt 54 as is the lever 53 of the driver operating mechanism.

(Fig. 5) the tacker head 92. To the support 84 just above its pivot 86 is attached a bracket 94 carrying one end of the driver spring 96 the other endof which is hooked through the lever 53 near its junction with the link 55 which connects it with the driver. From an inspection of Fig. 2 itwill now be clear that when the cam shaft 82 is rotated To the forward end of the lever 78 is rigidly secured by its sprocket chain connection with the main shaft 8 the cam 50 will act to raise the rear end of lever 51 and through the link 52, lever 53 and link 54: will raise the driver against the tension of the spring 96 and that when the cam roll on the lever 51 ridesoff the abrupt portion of the edge of cam 50 the driver will be released and will be forced downward by the spring 96 to drive a tack which is fed beneath the driver at each clevation thereof by mechanism to be subscquently described. The driver spring 96 being attached to the bracket 9% forward of the pivot 86 serves, besides the function de scribed, to keep the cam roll of the lever (31 pressed against the cam 60 thus tending resiliently to keep the tacker head in its rearward position while the cam 60 forces it positively forward.

The in and out or to and fro movement of the tacker head is produced by the earn (*3!) acting on the end of lever 61 fulcrumed on the rod 82 as stated. The forward end of the lever 61 carries a pin 62 (Fig. 2) which engages a slot ()3 in a rearwardly projecting arm 64 rigidly secured to the tacker head support 84: near its pivot 86. The cam 60 is shaped to oscillate the power end of lever 61 up and down once for each revolution of the cam shaft 82. This movement of the lever is communicated through the' connections described to the arm 64: which being rigid with the tacker head support causes it to swing about the pivot 86. As suming for thepresent that the lever 78 is rigid with the tacker head support 84, it will be seen that the nose of the tacker head is thus made to move about 86 as a center in an arc the horizontal component of which extends across the edge of the last. It is this movement which enables the nose of the tacker head to pass over the edge of the last and press the upper down upon the same. To facilitate this operation the tacker head is provided with a shoe or wiper 98 which is upturned at its forward end so as to avoid catching on the clamps about the edge'of the last, when these are used, during its iii-wiping and clown-rubbing action.

The up and down or rising and falling movement of the tacker head is communicated thereto from the lever 71 (Fig. which is oscillated by a cam similar in general to the cam 60. Upon the forward or inner end of the lever 71 is fixed at substantially right angles thereto and ofiset therefrom a T-shaped member 74 which has a slot 73 in the cross of the T adapted to en gage a pin 7 5 carried by the lever 7 8. Upon the rear end of the lever 71 is an extension 76 extending beyond the cam shaft 89 to which one end of a spring 79 is attached. The other end of the spring is secured to the tacker plate. The spring, being under tension, holds the cam roll on the lever 71 in engagement with the cam 70 and through the connection described presses the tacker head down upon the work. The spring, however, renders this pressure yielding and enables the wiper on the nose of the tacker head to wipe over the clamps and hold the upper resiliently until secured by a tack. The cam 70 acts upon the lever 71 against the spring 79 to raise the rear end of said lever and to depress the T shaped member upon the forward end and also the rear end of lever 78 which is connected therewith by the slot 73 and pin 75. The forward end of the lever and the tacker head which it carries is thus raised and, when the cam 7 0 allows the spring 79 to react, is resiliently depressed upon the work.

From the cooperative relation of the parts connected with cam 60 and those connected with cam 70 it will be seen that starting with the tacker head lowered and about to move forward over the last the cam roller on the lever 71 will be substantially at a dwell of cam 70 and the T-shaped member stationary. Upon movement of the cam 60 from this point the lever 61 is depressed and the tacker head support 84 swung about its center of rotation 86. Supposing for the sake of explanation that this circular motion were to be communicated in toto to the nose of the tacker, that is, with no movement of the lever 78 about its pivot, it would be necessary to have in the T-shaped member 74 an arcuate slot corresponding to the movement of the tacker nose. In that case however the motion of the tacker head would have a vertical and a horizontal component, the vertical being the greater. For the purpose of moving the tacker head over the edge of the last only the horizontal component is desired with a slight vertical movement to press the nose of the tacker firmly down upon the upper. To partly neutralize this vertical. movement, the slot 73 is made nearly horizontal but slightly in dined with its forward end the higher to permit depression of the tacker nose upon the upper when in tacking position and to neutralize an upward movement of the tacker due to the fact that the tacker support 84., being inclined to the rear when the tacker head is in retracted position, slightly raises the tacker head as. it swings forward toward the vertical and brings the tacker head into tack driving position. After the tacker head has completed its inward movement over the last in a nearly horizontal direction as described and the tack has been driven, the cam 70 raises the tacker head by depressing the T-shaped member and the cams 60 and 70 then combine to move the tacker in a backwardly and downwardly curved path to its starting point.

The tack feeding, separating, and delivering mechanism will now be described.

Mounted upon the outer portion of the lever 7 S whlch carries the tacker head on its inner end is a tack reservoir 100 from which a tack conduit 102 leads to a hopper 104.

' 104. The opposite end isheld depressed with the gate in position to close the conduit by a spring 110 held under tension between the end of the bar 106 and a pin 112 extending from the side of the hopper (Fig. 7.) A bar 114 (Fig. 4) is pivoted at 86 with the tacker head support and has a slot 116 which engages a guiding pin 118 on the hopper. The upper end of the bar 114 engages the gate bar 106 near its end. As the tacker head moves downward about the pivot 54 to tack driving position there is relative movement between the gate bar a 106 and the end of the bar 114, and the end of the gate bar abutting thereagainst is accordingly raised and the gate opened to allow tacks to pass from the reservoir 100 to the hopper 104. The end of the conduit 102 (Fig. 7) is provided with a slot 120 on its under side and the tacks passing from the reservoir fall through the slot 120 upon an inclined raceway 122. The tacks which have their ends properly directed enter the raceway 122 and move down it toward the tack separating device. The tacks which are not properly positioned to enter the raceway fall to the bottom of the hopper 104 and pass by a chute 124 to a receptacle 126 suitably mounted to receive them from which they may be returned at intervals to the reservoir 100.

The pick-oil lever 128 is pivoted to the front face of the tacker head at 132 and has its lower end extending to one side of the tacker head and bent rearwardly at right angles so that the tip of the lever which is provided with a notch 129 (Fig. 8) lies adjacent the end of the raceway 122 with its notch opposite the tack channel. The tip has also a downwardly projecting lip 133 on its under side to prevent the end of a tack held in the notch from swinging laterally during the motionof the lever. The notch 129 is adapted to contain the body of the lowermost tack in the raceway and is dis posed to one side of the center of the end of the pick-off lever so that when the end of the lever 128 is moved in the direction of the arrow from its normal position it will engage the lowermost tack with its notch and carry it to a position over the tube 130 leading to the driver passage while the unnotched position of the end of the pick-off lever will close the end of the tack raceway. As the notch of the pick-ofi passes, with its contained tack, beyond the end of the raceway the tack will drop from the notch or will be shaken ofit as the movement of the pick-off lever ceases and will enter the tube 130, which is preferably provided at its upper end, Fig. 13, with a funnel-shaped portion 131 having its side cut away to admit the lip 133 of the pick-0E lever. The pickoff lever is provided above its pivot with an irregular slot 134 having two portions parallel with 'the driver bar connected by an oblique portion. The slot is engaged by a pin 136 upon a block 59 clamped to the driver bar 57 as previously described. As the driver bar is raised by the cam 50 through the mechanism described, the pin 136 passes up along the first parallel por tion of the slot in the pick-off lever which remains stationary until the oblique portion of its slot is reached when the lever is oscillated upon its pivot to carry its notched end over the delivery tube 130. Then as the pin reaches the portion of the slot parallel to the first portion itsuddenly stops and remains stationary during the remainder of the upward stroke of the driver bar. The tack, having been picked oif and delivered to the tube 130 by the movements described, passes by gravity down the drive channel and is caught by the tack holding jaws 138 (Figs. 5 and 6) which are arranged to slide in and out in oppositeholes in the nose of the tacker head. The meeting ends of the jaws 138 are provided with tapered grooves to form a tack holding recess 139 (Fig. 6) and are held resiliently in their inner or tack holding position by leaf springs 140. Each of these springs is secured at one end to the tacker head and at the other end has a squared notch adapted to engage the squared end of one of the jaws 138, and to abut against a shoulder 142. The jaws are then held from rotation with the larger end of the tapered tack holding recess 139 uppermost.

During the passage of the pin 136 along the upper parallel position of the slot the tack is given time to pass down the tube and assume its position in the tapered tack holding recess 139 before the descent of the driver. As the driver bar descends the pin 136 restores the pick-off lever to its normal position with its notch opposite the raceway and the driver strikes the tack and forces itthrough the jaws, which yield outwardly to permit its passage, into the work upon the last.

By the mechanism thus far described the tacker head is given proper movements across, down to, and up from the last edge to act upon an upper and the nails are arranged, separated, delivered and driven.

The relative movements of the tacker mechanism and the last support whereby the tacks are properly spaced about the periphery of the shoe sole are now to be descrlbed. The tacker mechanlsm is mounted upon the plate 26'which is pivoted at its rear end upon the upper end of the arm 18 mounted on the rock-shaft 14. At its forward end the tacker plate is provided with a block 27 which is in sliding engagement with the top of the column 1 when there is no work beneath the tacker head. Forward of the standard 80 on the plate 26 is attached an out-standing arm 144 (Fig. 3) to which is pivoted a bar 146. The other end of the bar carries a bolt and thumb nut which engage a slot 150 in the lever 152 pivoted at 154 to the top of the column 1.. The opposite end of the lever 152 is pivoted to a block 156 which in turn is pivoted to the arm 158 (Fig. 9) which extends down within the column 1 through a slot 11 in its top plate 12 and is pivoted to a block 160 carrying a pin which engages a hole in the upper end of one arm 162 of a bell-crank lever pivoted at 164, the other arm 166 of which extends through an opening in the column 1 (Fig. 2) and rests upon a cam lever 168 intermediate the ends thereof. One arm of the lever 168 is pivoted to the standard 170 and the other carries a cam roll adapted to rest on a cam 172. A tension spring 174 is attached to a pin 176 on the arm 166 of the bell crank lever and to the base of the column 1 to hold the said arm against the cam lever 168. The cam 172 is fixed on the auxiliary shaft 10 journaled in the standard. 6, as described and has two projections and two depressions about its periphery so that it produces two complete oscillations of the cam lever 168 for each revolution. Fixed on the same shaft is a ratchet wheel 178 and loose on the shaft is the arm 180 carrying the pawl 182 in engagement with the ratchetwheel 178 and connected between the pawl and its pivot by the connecting rod 184 with a crank disk 186 on the main shaft 8. the disk 186 is provided with a diametrically disposed dovetail slot in which the wrist pin 188 is mounted for adjustment for the purpose of varying the throw of the pawl carrying arm 180 and pawl 182 so that the pawl may be made to pass one or more notches as the arm is reciprocated. The number of teeth in the ratchet wheel 178 corresponds to the maximum number of tacks to be driven about the periphery of the shoe sole. v

The operation of the above described mechanism is as follows: Supposing the main shaft to be rotated, the wrist pin 188 and connecting rod 184 will oscillate the arm 180 and cause the pawl 182 to rotate the ratchet wheel 178 one notch (if so ad j Listed) at each revolution of the main shaft, thus partially rotating the auxiliary shaft 10 and the cam 172 in counter clockwise di The face of rection. Rotation of cam 172 from the position shown in Fig. 2 and in the direction indicated will raise the cam lever 168 and the arm 166 of the bell-crank lever resting thereon against the spring 174. The other arm 162 of the bell-crank lever will thus be oscillated and the arm 158 will push the inner. end of the slotted lever 152 to the left in Fig. 3 and carry with it the end of the connecting bar 146 which is attached to the arm 144 on the tacker plate 26. The tacker head and its operating mechanism will thus be swung slightly to the left in Fig. 3 about the pivot 19 on the plate 20 and the next movement of the tacker head over the edge of the last will bring it into position to drive a tack at a point slightly displaced along the periphery of the last from the one last driven. This processive feeding move ment of the tacker head will continue until the cam 172 has completed a quarter of its revolution and reached the limit of its first forward throw, then the tacker will begin to recede or travel back and will, of course, make two journeys in each direction for one revolution of the cam 172. The tacker reaches the limit of its movement toward the toe, however, at the point where the outline of the shoe sole begins to bend around the toe and as it begins to travel in the 0pposite direction the last support and shoe begins to rotate, due to mechanism to be described, in a counterclockwise direction at a rate which carries the toe portion backward faster than the tacker head moves, thus effecting the necessary relative movements between the tacker head and shoe to carry the tacking mechanism about the toe pon tion. Upon the completion of a semi-revolution of the last support the toe will have been passed around and the tacker will be in position for movement along the second side of the shoe in the same direction as its first movement, but, as the position of the shoe is reversed, will, this time, travel from toe to heel. When it reaches the heel the shoe support will be given another half re volution to enable the tacker to pass around the heel in a manner similar to its passage around the toe. The length of the steps taken by the tacker head in its step by step movement along the edge of the last may be varied for different sized lasts by adjusting the end of the connecting bar 146 along the slot 150 in the lever 154.

The tacker head plate 26 is provided at its inner end with a gage or feeler 190 (Figs. 4 and 13) which engages the edge and top of the clamping plate or guide 191 which extends about the last to hold the upper in place or which may rest against the upper itself in the absence of the plates. The gage 190 acts as an edge gage to limit the inward movement of the tacker head plate so that the tacks are located at the proper distance from the edge of the last about the periphcry of the shoe. The gage rests upon the top of the clamp or guide 191 which thus sustains a portion of the weight of the tacker head and carries a downwardly projecting lug 193 (Fig. 13) which is made to press against the side of the last or clamping plates by a weight 192 on the end of acord 194 which passes over a pulley 196 and is attached to the tacker plate 26 near its rear end. The cord 194 passes also behind a pin 199 on the underside of the connecting bar 146 (Fig. 3) which arrangement properly directs the cord over the pulley and causes pressure on the pin to hold the tacker mechanism swung to the right in Fig. 3 thus assisting the spring 17 4. The feeler 190 serves as a rest for the tacker nose when the tacker is in retracted position, and as the tacker moves forward the nose is guided by the feeler over the guides 191 and under the impulse of the spring '7 9 slips off of the feeler and drops upon the upper with a blow, thus treating the upper by impact and beating it down upon the last. It then slides inward, wiping the upper down into position to be tacked. For moving the tacker mechanism backward out of the way of the last and support, a treadle lever 200 (Fig. 1) is provided pivoted about the main'shatt and carrying at its rear end a link 202 having a cylindrical upper portion extending through a hole 204 in a lever 206 fixed on the rockshaft 14, there being a shoulder on thelink 202 for engaging the end of lever 20 6. Pressure on the forward end of the pedal lever will obviously rock the shaft 14 and carry the arm 18, plate 20 and tacker head plate 26 pivoted thereto backwardly. The arm 18 is held from lateral movement by the guides 21. The cylindrical upper portion of the link 202 engaging the hole 204 in the lever 206 permits the tacker head to be moved back if desired without operating the pedal lever. I

The mechanism for rotating the shoe comprises a circular plate 220 which supports the jack and has its periphery divided into two portions of slightly diflerent diameters, the lower and larger portion having notches corresponding in number to the number of tacks to be driven about the heel and about the toe portions taken together. The plate 220 has a trunnion 218 inthe center of its under side which passes through the end of the carrier member 240. A ring 241 is secured upon the trunnion and holds a spring 251 compressed against the carrier member 240. The spring 251 then holds the plate 220 resiliently against the carrier 240. In-. termittent rotary motion is communicated to the plate 220 by connection with the main shaft best shown in Figs. 1 and 3. Mounted upon the main shaft 8 is an eccentric cam 226 which acts upon a bent lever 228. The

lever is held against the cam by a tension spring 229 attached at one end thereto be tween its pivot and the cam and at the other end to a pin on the column 2. Upon the upper end of the lever 228 is a device Fig. 12 comprising a plate 230 having a depend ing pin adjustably held by set screw 232 in a hole in the upper end of lever 228. The rear end of the plate 230 is upturned and has hinged thereto an upper plate 234. To limit the upward movement of the upper plate a stop 236 is attached to said plate, and has its lower end bent under the lower plate to limit the upper movement of the upper plate. A compression spring 238 suitably secured between the plates holds the upper plate against its stop but permits it to be depressed.

The jack carrier member 240 is mounted for rotation about its middle point upon the column 2. Duplicate jacks are provided,

one upon each end of the member 240 so that a shoe may be prepared for tacking upon one of the jacks while another shoe is being automatically tacked on the other jack. The carrier 240 (Figs. 1 and 10) is locked in position with either ack adjacent the tacker by a bolt 242 slidably mounted in a member 244 attached to the column 2 (Fig. 1) and upheld by a loose pin connection 245 (Fig. 10) with a lever 246 tulcrumed at 248 and held upward by a spring 250. The bolt engages a recess in the downwardly projecting trunnion 218of the jack plate and the end of the trunnion is beveled ofi so as to automatically depress the bolt 242 when brought in contact with the same, and allow it to snap into the recess therein. The bolt is drawn down for releasing the carrier by a rod 252, connected with the lever 246, passing through the pedal lever 200, and pro-- vided some distance below the same with a nut and washer. When the treadle is depressed the tacker mechanism is first moved back, as previously described, and then the lever encounters the washer and nut and withdraws the bolt to release the carrier 240.

As the jack is swung into position in frontof the tacking mechanism the end of the lever 256 which operates its rotatory mechanism encounters the plate 234, depresses the same and allows it'to snap back when passed. Subsequent movement, of the lever 228 will cause the said plate 234 to engage and operate the lever 256. Referring to Fig. 3, it will be seen that the part of the lever 256 engaged by the plate 234 is the downwardly directed end of a bell-cranklever pivoted at 258 to the ack carrier 240. The end of the shorter arm of the bell-crank lever carries a pawl 260 adapted to engage teeth formed in the larger peripheral portion of the circular jack plate 220. The pawl 260 is held against the teeth of the jack plate by a tension spring 262 attached to a projecting heel of the pawl and to the lever 256 near its pivot. A second pawl 264 is mounted on the lever 256 and is adapted to engage a ratchet wheel 266 mounted for rotation on the aXis of the jack carrier and having attached to its lower face the cam plate formed with opposite cam projections 270. As a move ment is given to the ratchet wheel 266 by the pawl 26% at each oscillation of the lever 256, the projections on the cam plate are periodically brought into contact with one end of a lever 272 pivoted intermediate its ends to the jack carrier and having its other end disposed above the larger peripheral portion of the plate 220 and in front of the pawl 260 which is high enough to engage it. When one of the cam project-ions 270 engages the end of the lever 272 the other end pushes back the'pawl 260 and renders it inoperative so that the jack remains tionary as it must during the tacking of the comparatively straight sides of the shoe from heel to toe or from toe to heel. W'hen, however, the toe or heel portion (as the case may be) is reached, the cam projection will, as the rotation of the ratchet wheel 266 continues, ride off the end of the lever 272 and permit the pawl 260 to again engage the teeth in the base plate of the jack and rotate it. A spring pressed pawl 273 is provided to prevent a backward movement of the jack plate 220. Similar rotating mechanism is, of course, provided for each jack. At the same time that the jack begins to rotate, the cam 172 on the auxiliary shaft 10 reaches the limit of its throw and begins to permit movement of the tacker head, due to the spring 174 and counter weight 192, in the same direction as the edge of the shoe next the tacker is being moved by the jack rotating mechanism. The motion due to the latter mechanism is, however, about twice that of the 'tacker head so the tacker head continues to move about the periphery of the last at about the same rate as before.

The mechanism for starting and automatically stopping the machine is as follows :A power driven pulley 280 is mounted loosely upon the main shaft 8 (Figs. 1 and 11) and has upon the face of the hub next the machine a plurality of ratchet teeth 282 adapted to engage an arm 2841 pro jecting from a yoke 286 the ends of which are pivoted upon a pin 288 passing through the main shaft. A spring (not shown) holds the arm of the yoke against the ratchet teeth when the machine is being driven. A lever 292 is pivoted to the base of the machine at 29 1 and has a projection 296 engaging a stop plate 298 for limiting its rotation in response to a spring 300 which urges it to the right in Fig. 11. The end of the lever 292 is beveled off so that when it is permitted to swing to the right (Fig-11) under the pressure of spring 300 its end engages the similarly shaped end of the arm 28% on the yoke 286 and forces the same away from the ratchet teeth thus stopping the machine. For throwing the lever 292 out of the way of the arm 28 1 for starting the machine the lever 292 is provided with a projection 302 having an inclined face which is adapted to be engaged by a pin 30 1 on one arm 306 of a bell-crank lever pivoted on the main shaft. The other arm 308 of the bell-crank lever is normally held, by pressure of the inclined projection 302 upon the pin 304, in an upright position but when swung to the left (Fig. 11) it presses the lever 292 back and frees the arm 284 so that it is spring pressed against the ratchet teeth 282. For swinging the arm 308 a slide rod 310 is provided having a handle 312 (Fig. 1.) within easy reach of the operator and carrying a pawl 31-1- (Fig. 1) held by a spring 315 in position to engage the end of the arm 308. Then the operator grasps the handle 312 and pushes itdownward and away from him, the pawl 31-1 engages the arm 308 and moves it to the left in Fig. 11. A catch 316 is provided near the handle 312 for holding the slide rod depressed and means is provided for automatically lifting the pawl 31%. to stop the machine when the tacking operation has been performed entirely around the shoe. A lever 318 is pivoted at 320 to an upright 322 and has at its rear end a pin 324: adapted to engage the edge of a cam 326 on the auxiliary shaft 10 which makes one revolution while the machine is going through the operation of tacking entirely around the last. The forward end of the lever 326 has pivoted thereto a detent 328 (Fig. 11) hav ing a stop 330 against which the detent is pressed by a spring 332 attached between a pin on the detent and a pin on the lever 318. When the machine is running the pin 333 on the pawl 314 is disposed over the end of the detent 328 so that the detent, when lifted, will engage the pin and lift the pawl. Fig. 11 shows the position of the stop mechanism when the machine is running but is about to be stopped. hen the cam 326 has rotated far enough. in the direction indicated by the arrow the pin on the lever 318 will reach the abrupt portion of the cam face and permit the rear end of the lever to be depressed by a spring 331 placed under tension between it and the base of the machine. The forward end of the lever presses the detent 328 against the pin 333 and raises the pawl 31 releasing the arm 308 which is carried toward vertical position by the pressure of the inclined projection 302 of the lever 292 on the pin 30 1 carried by the arm 306. The lever 292 under the pressure of the spring 300 is carried into the pat-h of the arm 28st which rotates with the main shaft and the said arm when it contacts with the beveled end of lever 292 is thrown out of engagement with the ratchet teeth 282 and the machine stops.

In the operation of the machine as a whole the shoe is prepared for tacking by lasting mechanism partially shown at the left of Fig. l and fully described in the application referred toabove but forming no part of the invention herein claimed. When a shoe is ready for tacking the operator depresses the pedal lever 200 which operates mechanism to withdraw the tacker head from contact with the shoe last tacked and to depress the locking bolt 242 and permit rotation of the carrier 240. The carrier is then rotated 180 to bring the shoe prepared for tacking into position adjacent the tacker and the shoe last tacked into position to be removed. Upon release of the treadle lever the tacker head is returned by the counterweight 192 into contact with the edge of the shoe at a predetermined point for example where the curve of the heel straightens into the shank portion. The operator now presses down the handle to start the machine. The tackerhead is moved across the edge of the shoe, wipes down the upper, tacks it in place, is raised, retracted and lowered. During the retraction of the tacker head the arm 180 and pawl 182 are moved to the left (Fig. 2) to rotate the cam 172 and, through the system of levers described, advance the tacker head toward the toe a distance equal to the space between two tacks. hen the tacker head has advanced in this manner along the side of the shoe to the point where the outline of the sole begins to bend around the toe, the last rotating mechanism is automatically thrown into operation and the shoe begins to rotate and the toe portion to travel backward toward the position initially occupied by the heel portion. At the said time, however, the tacker head begins to travel backward toward its initial position but at a slower rate than the periphery of the toe moves. The toe having been passed around and the opposite side of the shoe reached, the rotation thereof automatically ceases and the tacker head at the same time stops and resumes movement in the same direction as at first along the second side of the shoe, passing from toe to heel. WVhen the bend of the heel. portion is reached the shoe resumes its rotation and the tacker its return movement toward initial position at which it arrives when the heel has been passed around. During these movements of the tacker and shoe the cam 326 makes a single revolution and allows the pin 32% to ride off its abrupt portion which action results in the actuation of the stop mechanism as described.
